Specification of Letters Patent.

Patented Aug. 24, 1915.

Application led August 31, 1914. Serial No. 859,291.

T0 all whom it may concern.'

Be it known that I, JOHN B. CLERMONT, a citizen of the United States, and. resident of the borough andA county of the Bronx, city and State of New York, have invented certain new and useful Improvements in 1Windows, of which the following is a specilication.

illy `invention relates to windows, more particularly of the type known as double.- hung windows, in which the sashes under certain conditions are capable of swinging on horizontal pivots relatively to the casing and has for its object to improve the meeting rail construction thereof.

My improvement also contemplates the provision of openings in the upper part of the casing through which access to the usual interior overhead pulleys may readily be had and also includes a readily removable covering means for said openings.

Other objects of my invention will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings illustratingr an example of my improvement in which- Figure 1 is a sectional elevationv on the line 1 1 of Fig. 2; Fig. 2 is a cross section on the line 2-2 of Fig. 1; and Fig. 3 is an enlarged detail section.

`Tn the drawings 5 represents the window casing having a horizontal partition 6 at its upper portion forming the lower wall or bottom of a chamber 7 in which the pulleys 8 for the accommodation of the sash chains or cords 9 are located. The chains or cords 9 at one end are pivotally secured in pairs at 10 to the upper sash 1l and lower sash 12 respectively and at the opposite end are connected with sash weights V13 of any well known description. These sashes under certain conditions are thus capable of a pivotal movement relatively to the casing 5 in vertical planes or about the horizontal pivots 10 and may be normally maintained against such pivotal movement and in the vertical paths in any suitable or desired manner` as for instance by means of movable locking strips 14: and parting strips 15. In the form of window shown and commonly known as a double-hung window the chains or cords for one sash both pass to a sash weight or weights vertically movable at one side of the vany other way.

.ments are equally, well adapted for use in connection. with windows counterbalanced in The partition 6 is provided with openings 6a located in proximity to the pulleys 8 and through which access to said pulleys may be freely had without making it necessary to completely dismantle the window the said openings 6a being of relatively large dimensions for this purpose. openings 6"L may normally be closed or covered I provide a cover plate 16 preferably of metal and arranged to extend completely over the lower ends of said openings and preferably secured-to and carried by a filler strip 17, the latter being itself removably secured in the casing 5 in any suitable manner asby means of screws 18. The said strip 17, in addition'to carrying the cover plate 16 also serves to compensate for the difference in dimensions of the upper and lower sashes necessary to permit the upper sash 1l tobe swung on its pivotsl() relatively to the lower sash 12 when this is desired. Thus when the openings 62L are to be exposed or uncovered, all that is necessary is to lower the upper sash 11 and remove the screw 18 which leaves the filler strip 17 free to be taken out of the casing 5, the cover plate 16 being carried along with said filler strip. When it is again desired to close the said openings 6a the combined filler strip y17 and cover plate 16 are simply replaced and secured in position without requiring any special manipulation of the cover plate '16 which is returned to and removed from its operative position in the above described way. In its operative position the said cover plate 16 completely seals said openings 6a against the entrance of dust or other foreign matter land also renders the window lireproof at these points by y preventing drafts and the entrance of flames to the chamber 7.

As shown in the illustration the upper sash 11 is provided along its lower edge with a horizontal inwardly extending projection or meeting rail 19, the upper surface of which is formed with a preferably curved or concave groove or recess 20 and an inclined plane portion 21 extending length- In order that these v20 and plane portion 24 extending along the inner portions of the projections 19 and 22 respectively while the plane portion 21 and Abead 23 are located respectively along the free edges thereof as is clearly shown in .F ig. 2 of the drawings. '1`hus when the window is completely closed the projection 22 of the lower sash 12 will extend over the projection 19 of the upper sash 11 and the bead 23 will be located in the groove or recess 2O while the inclined plane portions 21 and 24 will be in surface engagement with each other so as to secure a perfect dust and weather-tight joint along the meeting rails of both sashes. It will be seen with this construction that the sashes may be freely moved relatively to each other in a vertical direction and that the meeting rails will become properly reengaged with each other each time the sashes are brought to their fully raised and lowered positions respectively to close the window. If it is desired to pivotally swing the lower sash 12 relatively to the upper sash 11 when the window is completely closed and the meeting rails 19 and 22 are in engagement with each other it is merely necessary to bring the locking strips 14 or analogous devices to an inoperative position after which the upper edge of the lower sash 12 is simply swung inward away from the lower edge of the upper sash 11. The portions 21 and 24 being inclined downwardly in this general direction will oier no resistance to this actuation of the sash 12 while the bead 23 will readily move out of the recess 20 without moving either the upper or lower sash in a vertical direction to any appreciable extent or without making it necessary lirst either to lower the upper sash or to raise the lower sash to disconnect the meeting rails as is the case in many existing constructions. The lower sash 12 may be quickly returned to its normal vertical position in the casing in the same way by simply reversing the swinging movement thereof and without necessitating any other actuation of either sash.

My improved arrangement is thus simple in construction and easy to operateand at the same timeperforms its intended functions with a maximum of elliciency and secured all the advantages of an interlocking of the meeting rails in the closed position of the sashes without lnecessitating any extendved separate actuation of the two sashesin a vertical direction when a pivotal separation thereof is desired.

It will, of course, be understood that my improved constructions may be readily and satisfactorily combined with windows ofa type other than that shown with the same degree of eiiiciency in operation assured. It will further be apparent that in some cases the bead 23 maybe located in the meeting rail 19 and the groove or recess located in the meeting rail 22 or in other words the illustrated position thereof reversed if this should for anyreason be found of advantage.

Various changes in the specic form shown and described may be made within the scope of the claimsl without departing from the spirit of my invention.

I claim: l n

1. In a window or the like, a casing provided with a chamber at its upper portion and having an opening in the bottom wall thereof whereby access to said chamber may vbe had, sashes vertically slidable in said casing, sash cord pulleys in said chamber accessible through said opening, a filler piece detachably and rigidly secured to the bottom wall of said chamber and arranged to arrest the upward movement of one sash and means carried by said filler piece and extending over said opening to cover same, said means being arranged to arrest the upward movement of the other sash at a point beyond that at which the upward movement of the lirst named sash is arrested.

2. In a window or the like, a casing provided with a chamber at its upper portion and having spaced openings in the bottom wall thereof whereby` access to said chamber may be had, sashes vertically slidable in said casing, sash cord pulleys in said chamber accessible through said openings, a filler piece depending from said bottom wall and rigidly and detachably secured thereto, said filler piece being arranged to arrest the upward movement of one sash and a plate carried by said filler piece and extending over said openings to cover same, said plate being arranged to arrest vthe upward movement of thel other sash at a: point beyond that at which the upward movement of the first sash is arrested. n

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. Y
